Where does the working pressure and resistance of property companies come from?

The work of the property is mainly maintenance, which is not timely and procrastinating. When handing over the house, the construction team has a warranty. But now, I don't need to talk about the relationship between the developer and the construction team. As you know, in order to grab the construction period, most projects have to be repaired. Although the developer deducted the project payment, because of their relationship, the maintenance was not serious and perfunctory. In addition, the maintenance is always the most when the house is delivered, and repeated maintenance has no effect. At that time, the delay left a bad impression on the owner, and no matter what happened in the end, the project money would eventually be returned to the project leader, and there were even many problems left over from maintenance. If the real project maintenance is not timely, the project payment can be deducted. I think if the maintenance is solved, the project warranty will not be so arrogant and the owner will not contradict it. Subsequent property fees are easy to collect, and later maintenance fees are not so much. I don't think this problem can be solved. Developers and engineering teams are birds of a feather.
